Leadscrews
Trapezoidal thread design. Use with metric leadscrew thread listed in separate category.
Material: KSM = Carbon Manganese Steel S300 Pb (11 SMn Pb37) / LRM = Bronze CuSn8P. Carbon Manganese steel can be welded but difficulties may arise with bubbling due to sulphur content. KSM: Manual control control only - low rotational speeds only - for clamping or locking functions - for receiving dead weights. LRM: Manual or powered control - low and medium rotational speeds - for working under load. For power transmission and continuous use always use bronze nuts not steel.

Bearings and Spare Parts
Where alternative parts are offered, we make no claims as to their suitability. Selection of the most suitable bearings and parts is the responsibility of the customer. We recommend you replace bearings with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.

3 Piece Thrust Bearings Open Type with Flat Washers
These bearings are designed so that when one ring turns, the other remains stationary. Some have a larger bore on one side allowing a shaft with no steps to pass through. Others will require a stepped shaft as they have the same bore on both races. Some have a reduced size OD on one race allowing it to sit into an unstepped housing bore, whilst others will require a stepped housing to allow one ring to rotate. Please be sure to take note of the figures shown for ID and OD of both races to ensure you select the correct bearing. This category may be available in the new MBA online store at
